If you just purchased a new HVAC unit to cool and heat your home, it will work well for you for a long time. Once the unit ages, however, you will start noticing some problems. Below are two of these problems so you will know what to do if something like this happens to your unit.

Not Cooling

If you notice your home is not as cool as it should be even though your HVAC unit is running, one thing that can cause this is a frozen evaporator coil inside the HVAC unit. If this is the problem, the refrigerant in the unit is likely leaking. This is because the unit uses refrigerant to keep the air at a constant temperature. Without it, the air can become too cold, which in turn causes the evaporator coil to freeze up.  

An HVAC technician, like those at Astro Air Inc, can repair the leak, add more refrigerant, and unfreeze the evaporator coil for you. Make sure you hire a professional to do this for you as a refrigerant leak is bad for the environment.

Another thing that can cause a unit not to cool properly is a bad condenser. This is because the job of the condenser is to dispel heat. When the condenser is not working, the heat will get out and into your home. Replacing the condenser will repair this problem.

Less Airflow

If you notice less airflow coming from the vents when your HVAC unit is running, this could be due to a clogged and dirty air filter. This is because air cannot get through a dirty air filter. Also, the air that does get through picks up the dirt, dust, and other debris. When this happens, these things blow into the air inside your home, which can cause sinus trouble or make someone's allergies much worse.

Remove the air filter and inspect it. If it is dirty, then you need to replace it. Write down the size of the filter so you will purchase the right one. If you have an air filter that you can clean, follow the manufacturer's instructions on how to properly clean it, and then put it back in.

Check the filter more often if you own pets that stay in the home, if someone in your home is a smoker, or during the summer when the temperatures are high.

Talk with an HVAC technician about this information. They can tell you of other common problems you can have with your unit. You should also set up regular maintenance with the technician. Maintaining the HVAC unit on a regular basis is the best thing you can do to keep the unit running well for a long time.
